Answer: U = 4, T = 47
Those triangles seems, that they are the same, so:
“u” will be 4.
Also, I think they are right triangles, so the angles will be:
(180, because sum of angles in triangle is 180, and the rest are other angles).
180 - 90 - 43 = 90 - 43 = 47
So the “t” will be 47 deg.
We do the same with second triangle:
180 - 90 - 43 = 90 - 43 = 47
So the unknown angle in second triangle is also 47.
Tip: Right angle is 90 deg.
Sum of angles in triangle is 180 deg.
Those lines in side of triangles, means that the length of sides of those triangles is the same.
